<P STYLE="margin: 0pt 8.9pt 0pt 0pt; font-size: 10pt">Tenaris S.A., together with its subsidiaries (collectively, &ldquo;Tenaris&rdquo;
or &ldquo;we&rdquo;), is a leading global manufacturer and supplier of steel pipe products and related services for the world&rsquo;s
energy industry and for other industrial applications. Our manufacturing system integrates steelmaking, pipe rolling and forming, heat
treatment, threading and finishing across 16 countries. We also have a research and development (&ldquo;R&amp;D&rdquo;) network focused
on enhancing product portfolio and improving production processes. Our team, based in more than 30 countries worldwide, is united by a
passion for excellence in everything we do.</P>

<P STYLE="margin: 0pt 8.9pt 0pt 0pt; font-size: 10pt">In addition, Tenaris supplies pipes and tubular components for non-energy applications
and are focused on developing and supplying products and services for low-carbon energy applications such as geothermal wells, waste-to-energy
(bio-energy) power plants, hydrogen storage and refueling stations, and carbon capture and sequestration. Through our integrated, worldwide
network of seamless and welded manufacturing facilities, service centers and R&amp;D centers, and a team of around 23,000 employees worldwide,
we work with customers to meet their needs, upholding the highest standards of safety, quality, performance and reliability.</P>

<P STYLE="margin: 0pt 8.9pt 0pt 0pt; font-size: 10pt">Our mission is to deliver value to our customers through product and process
innovation, manufacturing excellence, supply chain integration, technical assistance, and customer service, aiming to reduce risk and
costs, increase flexibility and improve time-to-market. Wherever we operate, we are committed to safety and minimizing our environmental

<P STYLE="margin: 0pt 8.9pt 0pt 0pt; font-size: 10pt">Tenaris&rsquo;s customers include many of the world&rsquo;s leading oil and gas
companies, engineering companies engaged in constructing oil and gas gathering and processing and power facilities, and industrial companies
operating in a range of industries. Tenaris&rsquo;s principal finished products are seamless and welded steel casing and tubing, line
pipe and various other mechanical and structural steel pipes for different uses. The majority of Tenaris&rsquo;s seamless steel pipe products
are manufactured in integrated steel making operations using the electric arc furnace route, with the principal raw materials being steel
scrap, direct reduced iron, hot briquetted iron, pig iron and ferroalloys. Tenaris&rsquo;s welded steel pipe products are processed from
purchased steel coils and plates. Only a negligible portion of Tenaris&rsquo;s products contain or may contain conflict minerals.</P>

<P STYLE="margin: 0pt 9.45pt 0pt 0pt; font-size: 10pt">We note that our RCOI can provide only reasonable, not absolute, assurance regarding
the source and chain of custody of any products that may contain conflict minerals. Under our RCOI processes, we request data from our
direct suppliers and those direct suppliers request similar information within their supply chains to identify the original sources of
any necessary conflict minerals. Such sources of information may yield inaccurate or incomplete information and may be subject to fraud.
Another complicating factor is the unavailability of country of origin and chain of custody information from our direct suppliers on a
continuous, real-time basis. The supply chain of commodities such as conflict minerals is a multi-step process, operating almost on a
daily basis, which involves smelters, refiners, shippers, traders and distributors. Since we do not have direct contractual relationships
with smelters and refiners, we rely on our direct suppliers to gather and provide specific information about the origin of any conflict
minerals (or products containing conflict minerals) supplied to us. We seek sourcing data on an annual basis from our direct suppliers,
we ask that the data cover the entire reporting year, and we seek to use contract provisions requiring the direct suppliers to promptly
update us in the event of any changes to the sourcing data.</P>
